本文通过合成孔径雷达（SAR）图像对南森冰架断裂进行了研究，从它在SAR图像中首次出现到2016年4月7日最终崩溃。Sentinel-1和Cosmo-SkyMed图像均已使用。首先，将图像重新映射到等距圆柱投影上;从这些图像中提取仅覆盖骨折的子集或图像集。然后将分割方案应用于图像序列，以产生仅增强骨折区域的二进制图像序列;从这些图像中，骨折区域的计算成为一项微不足道的任务。
This paper presents a study, by means of of Synthetic Aperture Radar (SAR) images, of the fracture of the Nansen Ice Shelf, from its first appearance in SAR images to the final collapse on 7 April 2016. Both Sentinel-1 and Cosmo-SkyMed images have been used. First, the images were remapped onto an equidistant cylindrical projection; from these a subset, or imagette, only covering the fracture was extracted. A segmentation scheme was then applied to the sequence of imagettes in order to produce a sequence of binary imagettes with only the fracture area enhanced; from these, the computation of fracture area became a trivial task.
